ADIS16480 gyro issue

I'm trying to read the gyro_x  OUT and LOW registers, but there is an awkward problem. There are continuous variable values unless the ADIS16480 has a fixed position without varying it.

I tried also to read the pitch, roll, and yaw, The values were good but there are some dropped readings.

I'm using the breakout board.

Any help!

  • 1- What is the reason for dropping readings in gyro?

    Thank you for clarifying this question.  I sort of thought that is what you mean, so I would start with the information I offered in my previous reply.  


    2- Why did the gyro readings drift ?

    No sensor, that I am aware of, has zero drift, so can you quantify the differences in your observation, between the evaluation system and your system?  In other words, how much is it drifting?  Can you share a plot or some data, which is easy for us to import into Excel for quick analysis?  To be honest, I would address the first problem (drop outs) before spending time on the drift.  Any observation and analysis of sensor behaviors will be handicapped if we cannot rely on communication integrity. We have run these units for days, at maximum sample rates, without losing a single data point, so when we encounter what appears to be a bad data point, we investigate it fully, before doing anything else.
